Gate
Excellent corrosion resistance for harsh environments
The valve is highly resistant to corrosion, making it suitable for use in acidic, alkaline, seawater, and sewage environments. It is adaptable to a wide range of applications, including municipal, chemical, and hydraulic projects, ensuring a longer service life.
Reliable sealing with adjustable compression
The valve features a rubber-metal hybrid sealing structure, which can be adjusted using the wedge block to ensure a tight seal. Even after years of use, slight leakage can be easily repaired and maintained.
Low operating torque with multiple actuation options
The valve is designed with a lightweight gate and minimal friction, ensuring that the manual operation torque does not exceed 100N. Multiple actuation options are available, including manual, electric, pneumatic, and electro-hydraulic drives, to meet the needs of different projects.
Lightweight structure for easy transport and installation
The valve body is constructed using stainless steel or carbon steel welding, with a weight that is about one-third of that of a cast iron gate valve. This significantly reduces transportation and installation costs, making it suitable for projects with complex on-site construction conditions.
Long service life and easy maintenance
The gate and guide rail contact area is minimal, reducing friction and wear. Stainless steel gates can last for over 15 years, and carbon steel versions last over 10 years. The valve is easy to maintain, with low operational costs and simple repair processes.
